After all, our goal here is to encourage and educate our consumers to be wise whenever they shop for their desired products. After all, it is an unpleasant sight that you will go to the market clueless.

Shopping for power tools is a bit complicated as these devices have unique operation and design. A rotary is no exception to this fact. Therefore, you should understand the basic concepts that revolve around it. In this way, you will get a unit that would suit your needs and preferences.

How to Choose a Rotary Tool

How to Choose a Rotary Tool

As we mentioned earlier, a rotary tool is a versatile arsenal that any DIYer and contractor should get. It is a great device that you can bring whenever big and heavy power tools would appear impractical. But of course, we all know that not all rotary tools have the same features and capabilities. In this case, it would benefit you if you know how to pick the right option for you.

Different Kinds of Rotary Tools

In the field today, you can see two variants of rotary tools. They are the core and cut-out models.

Basic Rotary Tools

The primary rotary tool has a compact size. Because of this, it is the best option that you can get if you are just typically working in your home. In short, it is the finest choice if you are a self-confessed DIYer and weekend warrior. But despite that, a primary rotary tool is excellent for making detailed works and artistic type of woodworking.

Overall, the primary rotary tool is ideal for shaping, cutting, engraving, and smoothing. Just take note that its pace might be slow as it has a small motor (around 1 amp). But definitely, such kind of capacity allows maximum flexibility and control over your work.

Cut-Out Rotary Tools

0n the other hand, a cut-out rotary tool is cumbersome and large, due to its inherently large motor. Most of the time, you can commonly use these rotary tools in commercial and professional applications. For instances, many contractors are using them in removing dry walls in large-scale home renovation projects. Because their size, controlling a cut-out tool might be a difficult task for amateurs.

The motor of a standard cut-out rotary tool ranges from 3 to 5 amps. This power allows them to tackle different materials in the site, even hard metals and composite wood structures.

Most of the cut-out rotary tools today come with various features. Such of these are the types of attachments and adjustability options. Therefore, you should always read the labels so that you will know the full capacity of the device.

Cordless or Corded

When it comes to power tools, the debate between corded and cordless options are seemingly never-ending. But for us, this matter should not be worth your time already. After all, each of these power options has specific applications in where they excel.


Specifically, a corded rotary tool will provide you unlimited power supply. As long as you will plug the cable into a reliable source of energy, a corded tool will run for as long as you want it to be. It is a great option whenever you will be dealing with tedious and incredibly detailed projects. But on the other hand, you should expect that corded models will limit your mobility. After all, they won't run unless you connect them to a power input.


On the other hand, cordless rotary tools feature an independent source of power, through the form of battery packs. Depending on the capacity of the unit, a cordless model will either have a big or small size. As we mentioned earlier, rotary tools that are compact and lightweight are easier to manoeuvre. They also have specific components that lessen the fatigue of the user.

Typically, cordless rotary tools have power outputs that range from 4.8 volts to 18 volts. That is equivalent to the 1 amp to 5.5 amps of corded rotary devices. You should look for a model that exhibits high power if you are planning to use it consistently.


The rate of a rotary tool is a crucial indicator of its performance and overall versatility. You can usually gauge the speed through RPM (revolution per minute). A cordless rotary tool can run as fast 5,000 RPM to 16,000 RPM. Meanwhile, a corded option offers a minimum speed of 5,000 RPM to a whopping 35,000 RPM.

But of course, all of this power is meaningless if you cannot adjust them. Therefore, it is pretty necessary for you to look for rotary tools that come with variable speed settings. In this way, you can augment the speed depending on the type of task that you are working. For instance, applying tremendous speed to a sensitive material is a bit overboard.

You should take note that a rotary tool that has a variable speed is a versatile option. It would allow you to accomplish various tasks, regardless of their nature.

Bit Size

You should also assess the compatibility of the rotary tool different bit shanks. Notably, versatile options have significant chunk sizes. The bigger the piece, the easier it is for the rotary tool to accommodate to smaller limbs. But of course, it is a given that they cannot cater those shanks that are larger than them.

In the market today, rotary tools have a standard of 1/8-inch to 1/4-inch shank compatibility. However, you can still see other units that have different shank capacities.
